SAW SET.

Application filed August 17, 1922. Serial No. 582,418.

T 0 all whom it may 007206771.

Be it known. that HENRY L. Qumran. a citizen of the United States of America. residing at Flagstaff, in the county of Coconino and State of Arizona, has invented new and useful Improvements in Saw Sets, of which the following is a specification.

The object of the invention is to provide a simple and efficient construction of manually actuable saw set having means for set ting and gauging the teeth of a saw so as to effect uniformity in. the setting thereof at any prescribed or necessary degree; and with this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings. wherein Figure 1 is a side View,

Figure 2 is a plan view, and

Figure 3 is an end view of a saw set embodying the invention applied in the opera tive position to a saw blade.

Figure at is a view of the device applied to the saw blade in a position to gauge or measure the degree of the set of a tooth.

Figure 5 is a detail view of the outer jaw detached from the shank.

Figure 6 is a view of the tool as applied to atooth to reduce the deflection thereof when it has been set to an excessive degree.

The tool consists essentially of a shank 10 having a fixed. preferably integral inner jaw 11 and an opposed preferably separate outer jaw 12 of which the ad'acent operative faces are spaced at an interval suflicient to receive the blade of a saw such as indicated at 13, with a portion of the face of the inner jaw disposed at an angle or in oblique relation with the body portion of the face thereof to form an anvil 14 in operative relation with which is arranged a hammer l5 pivotally mounted as at 16 upon the outer jaw and having at its outer end an impact face adapted to receive the blow of a hammer or like tool and provided at its inner end with a poll 17 to cooperate with the anvil in successively setting the teeth of the saw blade. The outer is preferably formed as a part of a yoke 18 adapted to be bolted or preferably rivetted as indicated at 19 to the side of the inner jaw so that it may be separately and differently tempered from the inner jaw. It is preferable that the inner jaw and related parts receive a hard and thereforemore or less brittle temper whereas the outer jaw is preferably provided with a less hard temper to render it tougher and less liable to fracture.

Mounted upon the end of the outer jaw and in a position to lock the hammer in an inactive or withdrawn position. is a cam 20. and mounted in the fixed or inner jaw preferably near the upper end of the anvil portion thereof is a gauge pin 21 consisting of a screw threaded in the jaw and provided at its outer end with a transverse screw driver kerf 22, a peripherally milled set nut 23 being threaded thereon to lock the gauge pin in its adjusted positions.

In trying or measuring the deflection of gauge of the teeth of a saw, the hammer having been withdrawn from its normal position in which it invades the space between the jaw faces, the flat face of the inner jaw is arranged in contact with the side surface of the saw and the teeth should just touch the extremity of the gauge pin. A very slight variation in the deflection of a tooth may thusbe noted and a proper remedy applied, and if the setting of a tooth has been excessive or beyond that which is desirable in order to secure uniformity in the operation of the saw, the deflection may be reduced by employing the kerf 24 formed at the rear end of the shank and which is adapted to be arranged in straddling relation with the overset tooth to permit of bending the same toward the plane of the saw blade.

The relation of the inner and outer jaws is such that when the tool is applied to the blade a slight upward movement of the free end of the shank will clamp the blade be tween the jaws so as to hold the tool in a fixed position while the hammer is struck to set a tooth on the anvil.

Having described the inventioin what is claimed as new and useful is 1. A saw set having spaced inner and outer jaws, with the former of which is connected an operating shank, the inner jaw being provided with an obliquely disposed anvil face and the outer aw with a pivotally mounted hammer provided at its inner end with a poll for cooperation with the anvil face and aving at its outer end an impact face, and a locking cam for securing a hammer in its inoperative position.

2. A saw set having spaced inner and outer jaws, with the former of which is con nected an operating shank, the inner jaw being provided with an obliquely disposed anvil face and the outer jaw with a pivot-ally mounted hammer provided at its innor end with a poll for cooperation with the anvil face and having at its outer end an impact face, and a gauge pin carried by the inner jaw and adjustably mounted thereon for terminal projection from the anvil face, and locking means for securing said pin in its adjusted positions. 10

In testimony whereof he afiixes his sieg nature.

HENRY I1. CAR-MAN.
